In data communication, cells are mini data packets with a fixed length and a limited number of information units.

In contrast to small data pack ets with a fixed length, there are data packets that have a variable length within their minimum and maximum lengths, these are called frames.

There are various transmission methods that use cells and are switched extremely fast using cell switching.
